What is the truth about tarpans? I have seen videos claiming that the animal in them is a tarpan, and that they are nearly extinct. Wikipedia says they have been extinct since 1909, if this is true, what are these other animals?

The Tarpan is a prehistoric wild horse type.
The Tarpan ranged from Southern France and Spain eastward to central Russia. Cave drawings of Tarpan horses can be found in France and Spain, and artifacts showing this breed can be found in Southern Russia where this horse was domesticated by Scythian nomads in about 3000 B.C.
The original wild Tarpan died out during the late 1800′s. The last Tarpan horse died an a Ukranian game preserve at Askania Nova in 1876.
